The Australian Legal System: An Overview for Newcomers
By international standards, Australia has a fairly complex legal system: there is federal law as well as the separate laws of each state and territory. Understanding the basic structure helps you know which part of the system you are in and where to turn when you need to.
This article is general information about how the system is structured, not personal legal advice.
Two layers of law: federal and state
Federal (Commonwealth) law applies across the whole of Australia. Examples include visa and immigration law, employment law (the Fair Work Act), consumer protection law (the Australian Consumer Law), and tax law.
State and territory law applies within each region and often differs considerably between states. Examples include residential tenancy law, road rules, some small-business regulations, and family law.
The practical consequence: your rights in some areas, especially renting, depend on which state you live in. You cannot look up “Australian” tenancy law in general. You have to check the law for the right state.
The common law system
Australia follows a common law system inherited from England. This means that, beyond written law (Acts of Parliament), court decisions also create law and are binding. Higher courts make rulings, and lower courts must follow them.
This can sometimes create a gap between what the written law says and how the courts actually interpret it.
Courts and tribunals
The justice system has several levels:
Courts: Handle more serious criminal and civil matters. The Magistrates/Local Court level deals with many smaller matters; the Supreme Court level handles larger ones.
Tribunals: Usually where common civil disputes are resolved, with simpler procedures than a court. Examples include VCAT (Victoria), NCAT (NSW), and QCAT (Queensland), which handle tenancy disputes, consumer disputes, and discrimination complaints. Many people encounter a tribunal before (or instead of) going to court.
Ombudsman: A body that investigates complaints about government agencies or a specific industry (energy, telecommunications, finance). Usually free and does not require a lawyer.
Criminal law vs civil law
An important distinction that many people confuse:
Criminal law: The state prosecutes an individual for conduct considered an offence against society. Police investigate, and prosecutors lay charges. Penalties can include fines, suspended sentences, or imprisonment.
Civil law: Disputes between private parties, such as contract disputes, claims for damages, property disputes, and divorce. There is no “defendant” in the criminal sense; the winning party is usually awarded money or an order to do or stop doing something.
Many everyday situations (tenancy disputes, claims for unpaid wages, consumer complaints) are civil matters. They do not need police involvement, and people resolve them themselves through the appropriate tribunal or court.
Key enforcement bodies
Fair Work Ombudsman (fairwork.gov.au): Oversees workplace rights across the federation. Receives complaints about underpayment, working conditions, and unfair dismissal.
ACCC (accc.gov.au): The federal competition and consumer protection body. Investigates commercial fraud and large-scale breaches of the Australian Consumer Law.
Consumer Affairs / Fair Trading (each state): Handles smaller-scale consumer disputes, tenancy, and licensing for some industries.
Australian Human Rights Commission (AHRC): Investigates discrimination complaints at the federal level.
Police: For criminal offences or when urgent protection is needed. Emergency number: 000. Non-emergency: 131 444 (the national standard for non-emergency police).
A practical takeaway
People usually do not need to go to court to resolve everyday legal problems. Most disputes, whether tenancy, employment, or consumer, have a path to resolution through a tribunal, an ombudsman, or direct negotiation supported by free legal services.
